Electric Current: Electric current may be described as the rate of flow of charge. I=q/T Where, I = electric current q = charge T = time The unit of current i
Two point charges q and -q are splitted by distance 2l. Find the flux of electric field strength vector across the circle of radius R placed with its centre coinciding with the cet
Define the term multi-mode fibre shortly. Multi-mode fibre: This type of fibre permits more than one mode to travel by this. As this has to permit more number of modes to tr
a wave of eqn y=0.005sin(8x-3t).find displacement when x=0.3 t=20s?in the answer given y=0.005sin(80*3-0.3*20)= y=0.005sin(-36+12pi).what is this 12pi?
Longitudinal Waves: The traveling waves in which particles of the elastic medium vibrate about back and forth along the direction of propagation of waves are called longitudina
